Question

A disulfide bridge is a unique type of _____ modification in which _____ bonds are formed between cysteine residues.

(a) posttranslational, covalent

(b) translational, covalent

(c) translational, ionic

(d) posttranslational, ionic

This question was posed to me at a job interview.

I need to ask this question from Post translational Modification topic in section Functional Genomics & Proteomics of Bioinformatics

Answer 1

The correct option is (a) posttranslational, covalent

Explanation: Disulfide bonds are important for maintaining the stability of certain types of proteins. The disulfide prediction is the prediction of paring potential or bonding states of cysteines in a protein.
